Influence of Pressure and Time on Extraction Process Using Supercritical Co2
(Technical Faculty, Bor-Serbia, Bor, 2008)
The supercritical fluid extraction (SFE) by carbon dioxide (CO2) of Salvia officinalis L. was investigated. SFE by CO2 was performed at different pressure (80, 100, 150, 200 and 300 bar) and constant temperature of 40 ...
Assessing the catalytic activity of three different sources of tyrosinase: A study of the oxidation of mono- and difluorinated monophenols
(Elsevier Science Inc, New York, 2008)
Tyrosinase (tyr) purified from Pseudomonas putida F6, Streptomyces antibioticus, and Agaricus bisporus (mushroom) oxidises 3 regioisomers of fluorophenol as well as 3,4-difluorophenol (3,4FP). The catalytic efficiency ...
Community structure and antibiotic production of Streptomyces nodosus bioreactors cultured in liquid environments
(Wiley-Blackwell, Malden, 2008)
Immobilized bacteria are being assessed by industry for drug delivery, novel fermentation systems and the protection of organisms in harsh environments. Alginate bioreactors containing Streptomyces nodosus were examined ...
Synthesis, structural characterization and cytotoxic activity of two new organoruthenium(II) complexes / Sinteza, strukturna karakterizacija i citotoksična aktivnost dva nova organorutenijum(II) kompleksa
(Serbian Chemical Soc, Belgrade, 2008)
Two new p-cymene ruthenium(II) complexes containing as additional ligands N-methylpiperazine ([(eta(6)-p-cymene)RuCl2(CH3NH(CH2)(4)NH)]PF6, complex 1) or vitamin K-3-thiosemicarbazone ([(eta(6)-p-cymene)RuCl2(K(3)tsc)], ...
The conversion of BTEX compounds by single and defined mixed cultures to medium-chain-length polyhydroxyalkanoate
(Springer, New York, 2008)
Here, we report the use of petrochemical aromatic hydrocarbons as a feedstock for the biotechnological conversion into valuable biodegradable plastic polymers-polyhydroxyalkanoates (PHAs). We assessed the ability of the ...
Up-Cycling of PET (Polyethylene Terephthalate) to the Biodegradable Plastic PHA (Polyhydroxyalkanoate)
(Amer Chemical Soc, Washington, 2008)
The conversion of the petrochemical polymer polyethylene terephthalate (PET) to a biodegradable plastic polyhydroxyalkanoate (PHA) is described here. PET was pyrolised at 450 degrees C resulting in the production of a ...
Hexaaquamagnesium(II) bis(D-camphor-10-sulfonate)
(Blackwell Publishing, Oxford, 2008)
The structure of the title complex, [Mg(H2O)(6)](C10H15O4S)(2), consists of regular octahedral [Mg(H2O)(6)](2+) cations and D-camphor-10-sulfonate anions. A three-dimensional supra-molecular architecture is formed via ...
Syntheses, characterization and antimicrobial activity of the first complexes of Zn(II), Cd(II) and Co(II) with N-benzyloxycarbonylglycine - X-ray crystal structure of the polymeric Cd(II) complex
(Elsevier Science Sa, Lausanne, 2008)
For the first time, complexes of Zn(II), Cd(II) and Co(II) (1-3) with N-benzyloxycarbonylglycine have been synthesized and characterized. The complexes adopt tetrahedral, pentagonal-bipyramidal and octahedral geometry, ...
Synthesis, NMR, DFT and antimicrobial studies of Zn(II) complexes with N-benzyloxycarbonyl-S-alanine / Sinteza, NMR i DFT proračunavanja i ispitivanje antimikrobne aktivnosti Zn(II) kompleksa sa N-benziloksikarbonil-S-alaninom
(Serbian Chemical Soc, Belgrade, 2008)
In this study, the first complexes of Zn(II) with the N-benzyloxycarbonyl-S-alaninato ligand (N-Boc-S-ala) were synthesized. The new complexes were characterized by elemental analysis, conductometric measurements, IR. ...
